The Meopta Meostigmat 92mm f/1.7 is an ultra fast projection lens.
No filter mount, no aperture and no helicoid.
It was used in 35mm film projectors with 62,5 mm mount.
After individual adaptation it can be used with modern DSLMs and DSLRs, also with 35mm frame sensors. Its image circle is normaly for 18X24mm format (35mm movie format), so APS-C, but it can also illuminate full frame sensors (24X36mm).
The barrel of this high speed lens is all metal. The flange focus distance is about 51mm.
Its weaknesses, by using this lens with a digicam, is the lack of of a diaphragm.
